Good app, great value.
Sucks....for those who don't have it
Rating 1 star: it does work on Fire HD. After that....
This is a crude and primative app. Function and layout limited.
I suggest something else such as SpydrSafe. This app locks any app from opening. I wanted a stand- alone encryption notepad with its own lock + SpydrSafe for double security - this app isn't it.
